Trials·2025

Training general surgery residents on a dynamic simulator for temporary vascular shunts (TVSs) was as effective as using cadavers. This cost-effective simulation method may improve trauma skills.

Area of Science:

  • Surgical Education
  • Trauma Surgery
  • Medical Simulation

Background:

  • General surgery residents have limited exposure to open trauma operative cases.
  • Simulation is crucial for practicing critical procedures.
  • Traditional static simulators lack realism for hemorrhage control.

Purpose of the Study:

  • To evaluate the effectiveness of a dynamic simulator versus a cadaver for training temporary vascular shunt (TVS) placement.
  • To determine if dynamic simulation is a cost-effective alternative for trauma skills training.

Main Methods:

  • A randomized controlled trial compared a dynamic simulator with ongoing hemorrhage to a cadaver arm for TVS placement training.
  • 54 general surgery residents were enrolled.
  • Trainees were tested on a live swine model, with performances evaluated by blinded surgeons.

Main Results:

  • Residents trained on the dynamic simulator placed TVSs faster than those trained on cadavers (584s vs. 751s).
  • There was a trend towards faster hemorrhage control with the dynamic simulator.
  • No significant difference was found in Objective Structured Assessment of Technical Skills scores between groups.

Conclusions:

  • Dynamic simulator training is noninferior to cadaver training for TVS placement.
  • Dynamic simulators with hemorrhage offer a cost-effective method to enhance trauma skills training.
